Abstract

La présente invention concerne une boîte de transmission pour un aéronef à voilure tournante. Cette boîte de transmission comprend au moins un système à vitesse variable qui optimise la vitesse du rotor principal pour différents régimes de vol, tels qu'un profil de vol stationnaire et un profil de vol en régime de croisière rapide, sur n'importe quel aéronef à voilure tournante, tout en maintenant une vitesse de rotor de queue indépendamment variable.
